After searching threads about correct pinion angles I am wondering about the working angles on my DS. Im running a SBC on a lowered short bed with a one piece driveshaft. I ordered a TKO 600 "KIT" that included a cross member. When I installed the motor/trans the angle was obviously wrong. Way too low in the rear. Called them and they said it must be my motor mounts. All new parts so I figured I would call other places that sell these sort of kits. Long story short American Powertrain was nice enough to tell me there cross member specs. I modified the crossmember to match. So here is were I am now

all measurements done at ride hight)

Engine/trans 5deg down at rear (trans is almost against floor w/low hump)
DS 1deg down at front
Rear 5deg up in front (using 2deg shims)

Using the Spicer calculator I get Operating angles of 4 in front and 6 in rear

Are these too high?
